File Sharing - Problem Copying Files With File Explorer

With Win7 support gone, I finally got 2 Win10 x64 Pro v1909 machines up and running. Like so many other Win10 users, I have struggled to get network sharing to work. I have Googled, read and followed countless procedures and suggestions over the past few weeks, ad nauseam. The only suggestion I got to work was to enable the less secure SMB 1.0/CIFS Client. I don't like this solution, but it worked.

My (old) printers are USB connected to my desktop and I can print to them just fine from the laptop. No problem.

My issue is with using File Explorer to copy files between the 2 systems using drag and drop. In short, I can drag a file FROM the other PC and copy it, but I can't drag a file TO the other PC and copy it.

When I try to drag a file TO the other PC, I get this red NO symbol:



Yes, I have set Advanced Sharing and Permissions to Full Control for these folders on both systems.



Am I still missing some setting, or is there a know bug/limitation?

It went through the settings in Option 1 in great detail. Only a few settings needed to be changed.

Most of the settings in the other Options either were already set or did not apply.

I scanned the other tutorials, but did not see any that applied.

Bottom line - I still have the same problem.

I don't understand why sharing has to be so difficult. My previous 2 Win7 PCs were shared with no problem. All I want to do is to be able to copy files between PCs with File Explorer.

Yes. This is how both PCs are set.



As I stated initially, I can use File Explorer to copy files FROM the networked PC to the one I am sitting at, but not vice versa. Both PCs behave this way.

I just stumbled upon a very interesting twist to my problem. If you look at the screen shot in my initial post, I got the red NO symbol trying to copy a file to a shared folder named Setup.

On a lark, I created a new folder under Setup named Sub Setup and as the screen shot below shows, I was able to copy the file into this new sub-folder. I'm Confused.



Similarly, I can't copy a file directly to the displayed Desktop folder, but I CAN copy a file to the desktop if I use the route \\LENOVOM83-WIN10\Users\username\Desktop

I hear you. As I said in my opening post, I've Googled countless posts from many sites with similar problems and numerous solutions that mostly don't help.

But you're right, tomorrow I could turn the PCs on and get different results. I have also experienced times where I can't even see the other PC in File Explorer and re-booting one or the other fixes it... until next time.

Like many other posts I've read, networking, file sharing and printer sharing shouldn't be this difficult or intermittent.

I wonder what my experience will be in the morning when I power them off later tonight. Dunno.

One thing I see you may be missing. Services.msc/ Run as Admin.
Function Discovery Provider Host must be set to Automatically start. Sometimes we need to restart this function if our client are not showing up.
Function Discovery Resource Publication: Same as above.

These two function must be running for your network to function. On all computer in the network, You should turn off SMB 1 you shouldn't need it if these two functions are running.

That's one of the first things I learned while Googling the problem. Both PCs are set to auto.



I'll check the rest of the things in your post in the morning.

On your shares and Security setting. I have found that setting up Users that "Authorized User" with full control is all I need to share. You must have the exact same User set up on each unit in the network exact same User Name and Password Exactly. a space or Capitol letter any difference in the user name or password will prevent connections. I know this as it took me a couple of days to find that on one unit had my User Name as Clinton J Wright and the rest had my user name as Clinton J. Wright. Now this worked in windows 7 and Windows 8.1, but Windows 10 would not accept it with out the period after the J. This common user does not have to be active or open, it only has to be a User on each computer. My Wife computer runs her User account and my User account on her computer is just there and I have full access to her shared files. One other thing My User Account on all computer is a Admin Account.

Each PC only has 1 user (admin) set up. I verified both are correctly entered.

When I powered up the PCs this morning, each one saw the other in File Explorer, no problem.

I still don't understand why I can't drag/drop to copy a file from one machine into the shared folder on the other machine, but I can drag/drop copy a file into a sub folder. I can work around the issue but I'm just curious why Win10 behaves this way.
